The row select step/delay control counter now begins to count up the 1 kHz input,
every pulse into the counter representing 1 msec. When the counter reaches 64 (64
msec), the step/delay control counter resets, terminating all stepping and delay
counting activity. The resetting of the system, after the 64 millisecond delay,
removes an INHIBIT signal to the program which allows the next sequence of opera-
tions to begin.
